Noise Measurements During Appraoch Operations on Runway 21R at Detroit Metropolitan Airport

Abstract

Aircraft noise and distance data were acquired at three locations under the instrument landing system localizer path to runway 21R at Detroit Metropolitan Airport preceding and during a three phase 'field evaluation of 3, 000 ft. glide slope intercept program' conducted by the FAA. During two ten-day periods of measurements, noise of all IFR approaches on runway 21R between the hours of 0600 and 2400 were recorded. Effective perceived noise levels (EPNL) and other noise measures were obtained for much of the recorded data; NEF values were then calculated from the EPNL data.
